The central thesis of *The Penumbra Unbound* is that it is the first English-language book-length study of the Neo-Taoist thinker Guo Xiang [1, 2]. The author explores Guo's philosophy of freedom and spontaneity, demonstrating its coherence and significance [1]. The book also examines Guo's influence on later Chinese philosophy, particularly Chan Buddhism, and considers the implications of his ideas on freedom versus determinism in comparison to Western philosophical positions [1].
The text highlights Guo Xiang's reinterpretation of the Tao, which he understands not as a metaphysical absolute, but as literally "nothing" [1]. This absence of anything beyond appearances forms the basis of Guo's theory of radical freedom, where phenomenal things are "self-so," self-creating and self-transforming without external justification [1].
